Usage and augmentation plan is presented in Section 2.05.6(3) of the permit application. There are 11 surface water rights which have the potential of being impacted by western Fuels operations at New Horizon Mine 2. These are upgradient of proposed Sediment Pond 007 at the site. There are 29 water wells adjacent to the mine sites. Of these, just two. W-009 and D-041 on Figure 2 of Tab 16, could be Impacted by future mining activities at the New Horizon 2 site. 'these two wells are 154 feet or less deep and derive their water from near surface aquifers. At the and of five years of operation, Western Fuels estimated that drawdown might be one foot within a 0.7 mite radius of the center of the New Horizon 2 pit. Western Fuels proposes, with owner consent. to monitor these wells to detect any Changes In their hydrologic conditions. Western Fuels-Colorado will use the following alternative water sources to mitigate any ground or surface water right impacts. Western Fuels has available 114.5 acre-feet of surface water, which Is a consumptive use credit ,associated with Western Fuels' ownership of V shares of the Colorado Cooperative Company (CCC). Nestern Fuels has an absolute 4 acre-foot Storage right for the 001 reservoir at the New Horizon l mining area and is projected to have 18 acre-feet of pit pumpage during the non-irrigation season available -12-
